Thank you.
So I will be sending 0.0989 BTC to that address, are you ok with that?

the OP has requested the release of the funds he sent to me (0.1 BTC) for security, and that results in the closure of this thread.

game sounds interesting.
I still read-read the other reviews,
and really want to play this game

I no longer hold any funds for this. This thread should be marked as closed until the OP decides to re-open it again.
The 0.1 BTC funds I was holding will now be used for this purpose: https://bitcointalksearch.org/topic/closed-648439
I guess it's better let the thread die, there is no more auction anyway and bumping it is pretty pointless. I will send more funds if I decide to try it anyway.

No I meant the other way around. This thread is still live, the other has ended. You have the funds for this one!
hm, my bad, I misread, sorry
I do have 0.1 BTC, holding it for security purposes. June 15, 2014, 03:24:20 PM

Edit: It was the other way around, I have 0.1 BTC, sent by kuverty, will be holding on for security purposes only. For this thread.

game looks interesting......
Why not try it out then

yeah creating fair game is important, I usually wont participate in a game that is not fair, lets come together and think of a way to help the OP improvise.
In my opinion, this game is already pretty fair. The OP cannot run away with the funds, as for he as an escrow (me). He has also deposited extra BTC as security. It's also provably fair. How much more fair do you expect it to be?

Can you see any problem with this arrangement?

Any feedback appreciated and welcome everyone who wants to play.

I revised the rules and made them more clear to attract more players. If you feel that the game has a significant flaw for you, please speak out! I want to create a fair game for all.
Thank you.
Thank you.

This game sounds fun.. I'm going to keep an eye on it 
Thanks, it is much appreciated!
I also edited the original post for some clarity and I do feel the game is vary fair now. It indeed is provably fair if everyone decides to keep their exact numbers secret until the end, but it is not a problem if not. I think the biggest bets would be hashed anyway.

yeah its a great idea, doing so I might invest my coins to try to win some, when you think you will create a fair system?
It is fair now, isn't it? Well, I can not rule out the possibility that I might cheat by looking at the plaintext bets but I want to continue this and keep this exciting and more importantly (I think), most bets will be hashed.
So you just select how many numbers you want, pay the amount of mBTC and post you numbers here in the thread - SHA256 hashed with a secret string only you know. Then at the end of the round, when no new participants are let in, you reveal the string that contains your numbers and produces the pre-published hash.

Anyone in?
You can use this website to calculate the hash: http://www.xorbin.com/tools/sha256-hash-calculator
Hash a string that contains your numbers and some secret password (not any password you use elsewhere), in an unambiguous manner, then post your hash here and you are in - check the rules.

Well, it could be provably fair if users paid and provided only salted hashes to whomever runs the game
That's a good idea! The website could do the hashing client-side, using a client-side randomly generated seed.
Or see https://lbaat.net/ , particularly the ability to "Send message to the future". I guess that just moves the trust from you to them (the people running lbaat can read the messages ahead of time), however.
Also I can now actually see this game working as a gambling site, too. Maybe sacrificing a little usability in favor of provable fairness is OK, not everyone needs to use hashes and the bitcoin crowd is generally pretty techy.
You can keep the secret in the browser's local storage, and have a button to "reveal guesses" or something which sends the cached secret to the secret. That hashing itself needn't be done by the user, just by his browser. This is the same kind of trust the blockchain.info wallet has - you trust its client-side javascript to know your private key and not to share it unencrypted with the central server.
For a forum game, the players are going to have to do the hashing and secret-caching themselves. But the kinds of people wanting to play such a geeky game are probably capable of that if you link them to a site that does sha256 for them...

As I said in the JD chat where you mentioned it, the biggest problem with this kind of a game is that somebody (presumably but not necessarily you) gets to see all the entries early, and can use that information to win.
I don't see how such a game can be made provably fair, which might make it difficult to get people to play.

Yes, provable fairness seems like a pretty much impossible thing to achieve with this type of a game. I guess a site could be possible anyway, but it would have to be built up slowly. If it is running properly, it would make no sense to cheat for a quick buck.
Well, it could be provably fair if users paid and provided only salted hashes to whomever runs the game, then they would have a set time to reveal their inputs in order to claim their winnings. Preferably everyone should publish the hashes then, or at least the non-hashed bets should be published before hash-using players publish their numbers in plaintext.
But that lends quite a bit of responsibility to the players, it should be doable anyway though. At least it can be done with this forum game.
Also I can now actually see this game working as a gambling site, too. Maybe sacrificing a little usability in favor of provable fairness is OK, not everyone needs to use hashes and the bitcoin crowd is generally pretty techy.
So, instead sending me the numbers you can pay and send me a SHA-512 hash of a string such as "1, 3, 10-14 entersomerandomstuffhere9quy4" or just publish the hash in a message, which is probably the easiest.
Dooglus, what do you think? Sorry for the confusing, stream-of-thought post.
